WINDOW ATTACHMENT.

Application filed June 4, 1926, Serial This invention relates to certain novel improvements in window attachments and more particularly to a window scaffold adapted for connection in supporting relation with a window construction on the eX- terior side thereof and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

The present invention contemplates a novel combination and arrangement of parts for detachably connecting the platform of the scaffold in position contiguous to the window sill of the window construction whereby the platform will be supported in such a manner as to permit one, with safety, to step upon the platform in position exterior of the window construction. In accomplishing this, manifestly, the platform can be utilized as an outside ice-box or for the purpose of supporting flowers and other like objects exterior of the window construction upon the platform.

It is an object of the invention to provide a device of this character to accomplish the above purposes and whereby the device will be extremely light thereby enabling the same to be attached to or detached from the window construction.

A further object resulting from the invention is the provision for attaching the platform in supporting position whereby the platform can be used in connection with windows varying in width.

(lther objects will appear hereinafter.

The invention consists in the combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings illustrating the preferred form of my invention and in which: I

Fi" 3 is a sectional tail view taken substantially on line of Fig. 2. V

F 4 s a ta l n v e (if-the n enti illustrating the same in applied po sition. r a ame-at ap i at on th invention 1 have illustrated in the drawings, Fig. 4, a window construction which ineludes the usual window sash 11 mounted fo ve ieal e re en guideways l No. 113,748. Renewed June 11, 19 27.

fined in the side plates 13 of the window construction 10. This window construction defines the usual sill 14 and sub-sill 15.

The preferred form of construction embodying the invention comprises a latticelike constructed platform 16 formed of flat light metallic strips 17 and 17 secured together in lattice-like arrangement through the medium of rivets 18. The outer end portions of the strips 17 are bent substantially at right angles as at 19, with respect to the main bodies of this strip. The opposite end portions of the strip 17 are likewise bent substantially at right angles with respect to the main bodies thereof as at and to these end portions 19 and 20 is secured through the medium of rivets 21 a binding strip 22 formed of light metal. This binding strip 22, together with the strips 17 and 1 7, defines a basket-like shaped platform herein indicated at 16. The inner end portions 23 of the end strips 2 1 of the strips 17, as well as the intermediate strip 24 of the strips indicated at 17 are bent downwardly to form abutment flanges 26 adapted for bearing relation with respect tothe face 27 of the sill 14. The remaining strips 17 have their inner end portions 28 in alignment with the lengths of these strips and are adapted. for hearing relation upon the top 29 of the sill 14.

The above construction concludes the preferred form of construction of the plat form and I will now proceed to describe briefly the means for attaching the platform 16 to the window construction 10.

The means for attaching the platform 16 in supporting relation with respect to the window construction 10 includes connecting bars 30substantially angular in cross section as best illustrated in Fig. 4 ofthe drawings. These connecting bars 30 are adapted when in operative position to have their inner flanges 31 disposed in hooked relation'with the outer guiding elements 32 of the upper window sash (now shown), of the window construction 10. i To the other fl angesBS of these connecting bars are pivotally connected adjacent theu'pper ends 34 thereof, link members 35. The outer end portions of these link members 35 are -pivotally connected to cooperating link members 36 as at These cooperating link members 36 have their end portions 38 bent to define books 39 which are adapted for hooked engagement with the forward face 410 of the binding strip 22 between certain of the strips 17.

The connecting bars 30 are forced into bearing relation with the guiding elements 32 through the medium of link members 41 and 42 having their outer corresponding end portions 43 pivotally connected to the opposite ends of the connecting bars 30 through the medium of pintles 44 carrying friction rollers 45 for rolling engagement with respect to the faces 46 of the guiding grooves 12. These pintles 44 connect these end portions of the link members 41 and 42 to the flange 31 of the connecting bars 30. The inner corresponding end portions 47 of these link members 41 and 42 are pivotally connected together through the medium of pintles 48 to which one end portion 49 of presser bars 50 are connected as best shown in Fig. 3. These presser bars, as best illustrated in Fig. 3, define inwardly inclined notches 51 which are adapted individually for the reception of a connecting pin 52 which detacliably connects the presser bars 50 together for the purpose of holding the connecting bars 30 in bearing relation with the window construction 10 with the flanges 31 thereof disposed in hooked relation with the guiding elements 32.

These connecting bars 30 are forced into bearing relation with the window construction through the medium of a jack 53 which acts upon the presser bars 50 to urge the link members 41 and 42 to act upon the connect ing bars 30 to force these bars into said bearing relation. This jack 53 includes a base.

54 adapted for supporting position upon the top 29 of the sill 14 and defines a threaded socket 54 as best illustrated in Fig. 2 of the drawings. Threaded in this socket 54 is a lifting screw 55 which has swiveled connection asat 55', to a substantially U-shaped head 56 supporting the connecting pin In applying the invention to the window construction the connecting bars 30 are mounted in position with the flanges 31 thereof disposed to the rear of and in hooked relation with the guiding elements 32. The jack 53 is now manipulated through the medium of the handle 53 to force the lifting screw into position to cause the connecting pin to move the presser bars 50 in an upward direction about the pintles 58 so as to urge the connecting links 41 and 42 to act upon the connecting bars 30 and force these connecting bars into bearing relation with respect to the window construction in, position for supporting the platform 16 exteriorly of the window construction.

After this has been accomplished the platform 16 is placed in position with the end portions 28 of the strips 17 resting upon the top face 29 of the sill 14 and with the flanges 26 in bearing relation with the face 27 of this sill.

After the platform 16 is disposed in the position above mentioned the link members 36 are pivoted in a direction to'dispose the hooks 38 thereof in hooked relation with the face 40 of the binding strip 22 between certain of the strips 17.

From the description herein it is manifest that the attaching means can be adjusted to various window sizes as it, will be noted in adjusting the connecting bars the hooks 33 can be disposed in hooked relation with the face 40 of the binding strip 22 between any of the strips 17 according to the position of the connecting bars 30.

From the above description the manner in which the invention is disassembled is self explanatory.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variations and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
